Abstract
Stimulated anti-Stokes Raman scattering experiments were performed with a Bessel pump beam in hydrogen gas in the pressure range from p=6X10^5 to 5X10^6 Pa . The interrelation between two conical Stokes modes and several anti-Stokes far-field rings could be explained if we take into account planar transverse wave-vector matching only. Planar and nonplanar transverse and longitudinal wave-vector matching are discussed in detail. The experiments are compared with numerical solutions of the coupled equations for Stokes and anti-Stokes fields.
